GBIF data
The specimen data retrieved from GBIF.org on 07 January 2020 (GBIF Occurrence Download https://doi.org/10.15468/dl.wghcks) were filtered by "Scientific name", (Andrenidae, Apidae, Colletidae, Halictidae, Megachilidae, Melittidae), "Continent" (North America), "Country or area" (United States of America), and "State province" (PENNSYLVANIA). We have become aware that applying the geography-based terms excluded numerous records from our search results (i.e., a record was excluded if any of these fields were empty/missing when a record was originally submitted to GBIF or if there was a misspelling/variant of the search term in any of these fields). Applying a polygon/shapefile for the state and adjusting "coordinateUncertaintyInMeters", in place of using geography-based terms, will return all records that contain coordinates within the state, regardless of how complete their other fields are. Combining this search strategy with searches that use a wider variety of geography-based terms -to retrieve records without coordinates or that have been incorrectly georeferenced -can be used to compile a thorough GBIF dataset. However, the addition of records from searches such as these is outside of the scope of the corrigenda.

Checklist taxonomy
The subfamilial classification within Apidae was intended to follow Bossert et al. (2019), however, Anthophorinae was omitted. Thus, all members of Anthophorini were intended to be included in Anthophorinae, not Apinae. Additionally, all members of Emphorini should be classified within Eucerinae, not Apinae.
The species group, viridatum, was unintentionally omitted from Lasioglossum (Dialictus) dreisbachi (Mitchell, 1960) in both the text and Suppl. material 1. Hoplitis (Hoplitis) anthocopoides (Schenck, 1853) is in the adunca species group, not Annosmia−Hoplitis. Furthermore, L. (Sphecodogastra) truncatum (Robertson, 1901) does not have a species group and is thus not in the calceatum group. Suppl. material 1 has been corrected per this information, and to fully reflect the checklist text, group names for six Lasioglossum spp. were also added: cephalotes group -L.

Literature review records
Typographical and formatting errors that were introduced to Suppl. material 10 when the file was reformatted for publication were corrected.

Checklist legend
Some of the citations of the Legend presented on page 17 were incorrectly formatted and/or had the incorrect year listed. The corrected legend is reprinted in full here for clarity and convenience: Legend: 1 = Donovall and vanEngelsdorp (2010)  The county records for each species have been corrected in Suppl. material 1 and Fig. 3. The following additional changes were made to the species records in Suppl. material 1 and Fig. 3, to accurately reflect data presented in the checklist text: Nomada imbricata Smith, 1854 -Lancaster County was added; Lackawanna County was removed. Nomada luteola Olivier, 1812 -York County was added. Osmia (Melanosmia) pumila Cresson, 1864 -Jefferson County was added; Juniata County was removed. Andrena (Andrena) cornelli Viereck, 1907 -Schuylkill County was added.
